The Critical First 30 Seconds of Sterile Field Setup

When a circulating nurse transfers a surgical pack into the sterile field, improper packaging design can cause sterile drapes or instruments to touch unsterile packaging edges, contaminating the entire tray and forcing an expensive abort.

Clean Peel Tyvek Header Pouches

SterileValley utilizes medical-grade DuPont Tyvek 1073B heat-sealed to thermoformed PETG or medical polypropylene rigid blister trays. Precision chevron peel pouches open cleanly without fiber tear or particulate shedding, allowing circulating nurses to deliver contents smoothly into the scrub nurse's sterile hands.

Sequential Inverted Tier Packaging

Tray contents are assembled in the reverse order of clinical use: the outer sterile table drape is on top, followed by prep towels, patient drape sheets, fluid suction tubing, and finally surgical instruments. This enforces strict aseptic discipline without requiring nurses to shuffle components on the back table.
